The chromic acid recovery system in passivation baths, either chromatized or hard chrome, is based on ion exchange systems with selective resins for the purification of the bath and subsequent concentration with vacuum evaporation.

Advantages

Improvement in production quality by keeping the bath concentration constant.

Reduction of the pollution load in the final discharges through the elimination of emissions of expended baths that contain high concentrations of pollutants.

Cost reductions through the recycling of processing baths and in terms of the production of the baths and the derivatives from the treatment.
